Here's the case:
PersonA is BCC'd on an email because sender does not want others to know that Person A is getting the email.

I read about MailTips being able to put up a warning if PersonA  hits ReplyAll

I can not find any info on how to sset this up

This option is only available in Outlook 2016 and 2019. This can be done by creating the rule. Please check the complete information here: https://www.msoutlook.info/question/you-may-have-been-bcced-warning

No need to do this, as the recipient will be unable to reply all to a BCC. Message will only go to original sender
That is not the issue.  It is a person who does not realize they are listed as a BCC replying to all.  A BCC recipient can press REPLY TO ALL and everyone will see that response.


We created a rule which I will place here.
